MECHANISM FOR DIRECT MECHANICAL ADJUSTING OF THE ABUTMENT FOR THE THREAD GUIDES OH FLAT I-IOSIEI-EY FRAMES.

Application filed February 4:, 1926, Serial No. 85,938, and in Germany April 20, 1925.

Means have become known which carry out automatically the adjusting of the thread guide stops for design thread guides. These means are however very complicated as re gards construction and operation, so that the cost of manufacture and of maintenance is rather high and that further, owing to the mass inertia of the operative eleinentsthey prevent an easy and rapid running of the machine. This invention has for its object to obviate the inconveniences mentioned by using a chain as adjusting means for the thread guide stop. The chain is conveyed by a 1.)[UVl-Cl1lVll1g mechanism of known type which is capable to move the chain in both directions in accordance with the pattern, a rapid running of the machine free from shocks being ensured owing to the little mass.

An embodiment of the invention is diagrammatically illustrated, by way of example, in the accompanying drawing, in which F l shows'the corresponding portion of the frame in front elevation. V

Fig. 2 is a plan view of Fig. 1.

Fig. 8 shows by way of example a special form of the eccentric.

The abut-ments 1 are arranged on either side of the arm bar on a bar 2 and they are 139 each connected to a chain 3 which is guided over two pulleys l, 5 mounted on bolts 6 and 7, fixed on the bar 2. The bolt 6 carries a feed wheel 8 which is adapted to be rotated one or several teeth from an eccentric 11 to the right or to the left. 'By this feeding mechanism the abutments 1, through the intermediary of the chains 3, are moved away from or towards the centre of the machine so that the movement of the thread guide 10 takes place at another point if the adjusting 40 is carried out once at a movement of the thread guide bar 9 to the right and left. If the abutment l is also shifted between the right and left movement of the thread guide bar 9 the travel of the thread guide 10 which is fixed on the bar 9 may be made longer or shorter.

The eccentric 12 shown in Fi 3 may, for instance, be used as an abutment in being arranged fixedly or rotatably in front of the projecting parts 13 on the bar 9 which carries the guides 10 for the pattern threads. By slow, and if necessary intermittent rotation of this eccentric, the travel of the thread guide becomes gradually longer and then 6:} shorter again, so that the pattern will be in accordance with the shape of the eccentric.

I claim An adjusting mechanism for the thread guide stops on flat hosiery frames, comprising in combination with the design thread guides, stops for said design thread guides, endless chains for each stop, sprocket wheels for moving said chains, ratchet pawls, and

ratchet wheels for rotating said sprocket wheels in accordance wit-h the pattern so that the stops in the hosiery frames are adjusted accordingly in the inward or outward direction.

In testimony whereof I afiiX my signature. 7
